The S&P/ASX 200 Index (ASX: XJO) is in the red on Tuesday, now trading at its lowest level since October 14.
At the time of writing, the ASX is down 1.15% at 8,248 points, marking a tough session for the benchmark index.
Zooming out, the index – which tracks Australia's largest 200 listed companies by market capitalisation – is up nearly 9% this year.
Having retreated from all-time highs last week, why are investors selling down the ASX 200 today? Let's take a look.

Wall Street's dip flows onto the ASX 200
A significant sell-off on Wall Street overnight is likely to have triggered the decline in Aussie stocks today, with the US Dow Jones and S&P 500 indices retreating from their recent highs.
According to Bloomberg, rising US bond yields, with the 10-year yield approaching 4.2%, have stoked fears of resurging inflation, unsettling global markets.
Yesterday's decline in the US markets ends a nearly month-long winning streak for the S&P 500 Index (SP: .INX), which is up more than 23% this year.
The rally began in October 2023, when the US Federal Reserve signalled it would halt its interest rate hiking cycle.
Just as in today's price action, global stock markets followed suit, with ASX 200 shares notching a series of all-time highs throughout 2024.
It's not surprising to see this correlation on the downside as well.
All sectors are down
As such, the sharp sell-off in the US has spilled over to Australian markets, affecting every sector. At the time of writing, all 11 sector groups are in the red.
Tech stocks, which often follow the movements of their US counterparts, have taken the biggest hit. The ASX All Technology Index (ASX: XTX) is down nearly 1.4% on publication.
But it's not just the US weakness that's got the ASX 200 down today. The Australian index is heavily weighted to a few companies, several of which are in the red today.
CSL Limited (ASX: CSL), National Australia Bank (ASX: NAB) and ANZ Group Holdings (ASX: ANZ) make up over 9% of the ASX when combined. Each is down significantly, as seen in the table below. Data is obtained from CommSec.
Furthermore, tech company WiseTech Global (ASX: WTC) is embattled in its own internal dramas, with shares down nearly 4% on the day.
It holds nearly 1% of the ASX 200's weight as well, creating a notable impact.
Meanwhile, the mining giants, including BHP Group Ltd (ASX: BHP) and Mineral Resources Ltd (ASX: MIN), have also slipped amid softer commodity prices, contributing to the overall market downturn.
In short, a series of unfortunate events for major constituents of the ASX 200, compounded by weakness in the US markets, has led to a sea of red for Aussie investors today.

| CSL Limited (ASX: CSL) | 6.18% | -2.45% | +3.80% |
| National Australia Bank (ASX: NAB) | 4.95% | -1.80% | +26.87% |

ASX 200 takeout
While the ASX 200 has managed to climb nearly 9% year to date, today's dip serves as a reminder that markets move in cycles in the short term.
Despite today's blip, it's essential to remain focused on the long term and use such instances as opportunities when possible.
